1、JIANGXIAGRICULTURALUNIVERSITY本科畢業(yè)論文(設(shè)計(jì))題目:液壓挖掘機(jī)學(xué)院:工學(xué)院姓名:學(xué)號(hào):專(zhuān)業(yè):機(jī)械制造及其自動(dòng)化年級(jí):機(jī)制1004指導(dǎo)教師:職稱(chēng):導(dǎo)師1摘要全套圖紙,加本次畢業(yè)設(shè)計(jì)的題目是履帶式液壓挖掘機(jī)功挖掘機(jī)。和其他類(lèi)型的比較,類(lèi)似于這種類(lèi)型的挖掘機(jī)性能良好并且應(yīng)用廣泛,軟土地表面或沼澤地面也可以行使使用,并且可以減少對(duì)地面的壓力。液壓挖掘機(jī)的主要特點(diǎn)是:可無(wú)級(jí)調(diào)速,調(diào)速范圍大,能得到較低的穩(wěn)定轉(zhuǎn)速,動(dòng)作快,液壓元件的運(yùn)動(dòng)的運(yùn)動(dòng)慣性,加速性能好,并能高速反轉(zhuǎn),傳輸是非常順利,非常簡(jiǎn)單的結(jié)構(gòu),可吸收的影響和振動(dòng),操作省力,易實(shí)現(xiàn)自動(dòng)控制,易于實(shí)現(xiàn)標(biāo)準(zhǔn)化,系列
2、化,泛化。本設(shè)計(jì)斗容量是Q=0.2m3,它屬于小型液壓挖掘機(jī),工作裝置的傳動(dòng)原理,液壓挖掘機(jī),主要設(shè)計(jì)。本次畢業(yè)設(shè)計(jì),選擇為履帶式的液壓挖掘機(jī),為了滿(mǎn)足要求。在轉(zhuǎn)盤(pán)上表面是整個(gè)旋轉(zhuǎn),因此它可以在更大的范圍內(nèi)工作。由于采用液壓傳動(dòng)與控制可以提高整體性能。隨著現(xiàn)代挖掘機(jī)相比,開(kāi)采量增加到2~183倍,質(zhì)量大約是6噸,挖掘力約為30kN,排放的最大高度約為2.65m,最大挖掘深度4.2m,最大挖掘半徑大約是5.728m,可從機(jī)器的操作能力有了很大的提高,不僅挖掘能力大,和機(jī)器的重量,傳動(dòng)平穩(wěn),工作效率很高,結(jié)構(gòu)緊湊ABSTRACTThetopicofthisgraduationdesignism
